ABSTRACT A portable chain saw sharpening kit comprises a sharpener body in the form of an inverted U-shaped channel-defining member adapted to be placed over the bar of a chain saw, a rotary burr with a tapered abradant end portion which is receivable in a selected one of two horizontal guide bores provided in the sharpener body, and an alignment pin which is likewise receivable in a selected one of the two guide bores. The alignment pin comprises a shank portion and a reduced end portion, the latter providing an abutment surface for positioning a cutting link within the sharpener body channel in the proper position for sharpening. The shank portion and reduced end portion of the alignment pin are prefer- ably cylindrical and have different diameters, with the reduced end portion being eccentrically offset from the shank portion and having a diameter substantially equal to the widest diameter of the tapered abradent end portion of the rotary burr.
